Detailed description

Ectopic overexpression of the PR P23 osmotin-like protein confers to some transgenic lines higher tolerance to the oomycete pathogen Phytophthora citrophthora, as shown in challenges performed under greenhouse conditions with potted propagations of the sweet orange transformants.
All transformed plants are also carrying uidA and nptII transgenes conferring β-glucuronidase activity and resistance to kanamycin, respectively. (JRC 2008)
